Didn’t Sydney Sweeney star in this movie earlier this year

Yeah both films seem to be basically the same. Similar anti-Catholic pro-choice feminist message and premise.

They're so similar it's hilarious.

I like the fact both their wikipedia pages have this blurb;

Comparisons to The First Omen

Due to sharing similar premises (and a common Italian setting) and released at about the same time, Immaculate and The First Omen have been dubbed as "twin" films. Both films explore the issue of female bodily autonomy, depicting the "systemic control of women's bodies reduced to vessels". Bilge Ebiri of Vulture wondered about "why should anyone be surprised that suddenly, in the wake of the Supreme Court's overturning of Roe v. Wade, as state after state attempts to enact religious laws depriving women of bodily agency, America is getting horror movies about people forced into monstrous births by religious institutions worried about their growing irrelevance".
